The 10 factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, 81, and 162.

The factor pairs of 162 are 1 x 162, 2 x 81, 3 x 54, 6 x 27, and 9 x 18.

The proper factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, and 81 or,

if the definition you are using excludes 1, they are 2, 3, 6, 9, 18, 27, 54, and 81.

The prime factors of 162 are 2, 3, 3, 3, and 3. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.

The distinct prime factors (listing each prime factor only once) of 162 are 2 and 3.

The prime factorization of 162 is 2 x 3 x 3 x 3 x 3 or, in exponential form, 2 x 34.

NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
